And stay away from switching power supplies, if you can. They've come a long way in the last 30 years, but give me a solid linear transformered supply anytime, over a switching.
I was asked, yet another weird question, of how I would like to be buried, when I finally bite the big one. The answer was actually pretty easy. Face-down, like a certain historical figure in the late 1980's, (I will not mention who, but some of you will get it, and that's enough.) Why??? It would be a burial that will satisfy everyone: (1) My enemies will say that it will show me where to go. (2) On the same point, I can have my enemies kiss my butt. (3) It will temporarily give someone a place to park a bicycle. See??? A WIN / WIN for everyone.

Gee, it's almost as if this place could use a sticky where pdfs on interesting topics could be found categorised by topic!

:D
